That is what I thought, too. The fixes that Frank made requires only C++11 from 
what I understand, except that C++17 comes in when using variants, though there 
is an easy workaround to use external ones. Your idea of letting Bison to keep 
track of the type does not work in mid-actions as it is needed to decide which 
copy constructor to use, unlike C then.
